Textual Paint
=============

MS Paint in your terminal.

This is a TUI (Text User Interface) image editor, inspired by MS Paint, built with [Textual](https://textual.textualize.io/).

<!-- GitHub doesn't support line-height style in markdown, so I can't use inline HTML for the screenshot without seams between rows of text. But I can include the HTML inside <foreignObject> in an SVG file and include that as an <img> element. -->
<!-- GitHub doesn't support figure/figcaption in markdown, so I have to use a table. -->
<table>
<tr><td align="center">
<img src="screenshot.svg" alt="MS Paint like interface" />
</td></tr>
<tr><td align="center">This screenshot of Textual Paint is the terminal's screen buffer copied as HTML, wrapped in SVG, placed in HTML inside Markdown.<br>This might not render correctly in your browser.</tr></td>
</table>

## Unicode Symbols and Emojis for Paint Tools

The first thing I did in this project was to collect possible characters to represent all the tool icons in MS Paint, to gauge how good of a recreation it would be possible to achieve, starting from looks.
Unfortunately, I haven't run into any significant roadblocks, so I'm apparently recreating MS Paint. [Again.](https://jspaint.app)

These are the symbols I've found so far:

- Free-Form Select:  ✂️📐🆓🕸✨⚝🫥🇫/🇸◌⁛⁘ ⢼⠮
- Rectangular Select: ⬚▧🔲 ⣏⣹
- Eraser/Color Eraser: 🧼🧽🧹🚫👋🗑️
- Fill With Color: 🌊💦💧🌈🎉🎊🪣🫗
- Pick Color: 🎨💉💅💧📌📍⤤𝀃🝯🍶
- Magnifier: 🔍🔎👀🔬🔭🧐🕵️‍♂️🕵️‍♀️
- Pencil: ✏️✎✍️🖎🖊️🖋️✒️🖆📝🖍️
- Brush: 🖌️🖌👨‍🎨🧑‍🎨💅
- Airbrush: 💨ᖜ╔🧴🥤🫠
- Text: 🆎📝📄📃🔤📜AＡ
- Line: 📏📉📈⟍𝈏╲⧹\⧵∖
- Curve: ↪️🪝🌙〰️◡◠~∼≈∽∿〜〰﹋﹏≈≋～⁓
- Rectangle: ▭▬▮▯🟥🟧🟨🟩🟦🟪🟫⬛⬜◼️◻️◾◽▪️▫️
- Polygon: ▙𝗟𝙇﹄』⬣⬟🔶🔷🔸🔹🔺🔻△▲
- Ellipse: ⬭⭕🔴🟠🟡🟢🔵🟣🟤⚫⚪🫧
- Rounded Rectangle: ▢⬜⬛

The default symbols used may not be the best on your particular system, so I may add some kind of configuration for this in the future.

### Cursor

A crosshair cursor could use one of `+✜✛✚╋╬`, but whilst that imitates the look, it might be better to show the pixel under the cursor, i.e. character cell, surrounded by dashes, like this:

```
 ╻
╺█╸
 ╹
```
